To install the exhaust grommet for Mercury part number 75:
1. Lubricate the rubber grommet to ease installation.
2. Slip the grommet over the control cables.

Hei I have alarm going on my Optimax 75 I have mounted an smart craft and The alarm says: Pilot water pressure. Can it be the sensor that is wrong?? I have messured the water outlet to 4 liter pr min. at idle and 6,5liter pr min at 1800 - 2000 RPM. If I have to change the sensor, where is it located? Hope you can give me a good answer, and advise what I shoould do. Thank you.
The pilot water pressure alarm on a Mercury Optimax 75 could be caused by a blocked or faulty water pressure sensor, debris such as sand or silt in the sensor or hose, or a worn impeller. The water pressure sensor is connected via a gray hose, which can become partially blocked, affecting pressure readings. The sensor is typically located at the top of the gray hose near the engine, and the bottom of the hose connects to a T fitting. Replacing or cleaning the sensor and hose, and checking the impeller, may resolve the issue.
